存储过程在 SSMS 中执行时都返回结果，但从代码执行时只有一个返回结果

【中文标题】存储过程在 SSMS 中执行时都返回结果，但从代码执行时只有一个返回结果

【英文标题】：Stored procedures both return results when executed in SSMS but only one does when executed from code

【发布时间】：2015-10-14 04:55:51

【问题描述】：

我有两个存储过程，它们都是用 SQL Server 2012 编写的，并且都在 SQL Server Management Studio 中执行，它们将结果生成为 xml。

但是，当这两个过程被导入到实体数据模型中，然后它们所映射到的函数被调用时，只有一个会产生与从 ssms 执行时相同的结果。

我认为这一定与其中一个输入参数有关，但鉴于它们并没有那么不同，我不知道为什么会发生这种情况。

这两个存储过程如下所示。 SPA 在从两种环境中执行时都有效，SPB 在 ssms 中执行时运行，并在参数对话框中输入日期值，如“2015-07-05”，但在添加为日期值时失败（源自日期下拉控制）产生这样的参数 #5/7/2015 12:00:00 AM#。

任何人都可以发现我在 spb 中的一些明显的错误，这些错误会在从代码调用时阻止它执行，但仍然允许 ssms 正确执行它。

当从 SSMS 执行时，SPB 会产生以下结果：

  </Owner>
</PurchaseOrders>

当通过模型中创建的函数从我的应用程序执行时，它会生成以下内容；

<PurchaseOrders/>

我欢迎任何建议。

这是 Devart 的 SPA 实体开发人员创建的代码

            If (startDate.HasValue) Then
                startDateParameter = New ObjectParameter("startDate", startDate)
            Else
                startDateParameter = New ObjectParameter("startDate", GetType(Global.System.Nullable(Of System.DateTime)))
            End If
            Dim endDateParameter As ObjectParameter
            If (endDate.HasValue) Then

        End Function

它在我的代码中是这样调用的：

 Using ftpe = New FishTrackerProfessionalEntities
        Try
            Dim result = ftpe.CreateErsSalesAddSubmissionXmlByDateRange("uname", "pword", "B", "INSERT", String.Empty, String.Empty, ErsStartDate, ErsEndDate)
            xmlValue = String.Join(String.Empty, result.Select(Function(r) r.XMLF52E2B6118A111d1B10500805F49916B))
        Catch Ex As Exception

ErsStart 和结束日期是绑定到日期编辑控件的 Date 类型的属性。

对于 Spb，我们有：

Public Overridable Function GetLandingsToBePurchasedByDateAndPln (ByVal startDate As Global.System.Nullable(Of System.DateTime), ByVal endDate As Global.System.Nullable(Of System.DateTime), ByVal VesselPln As String) As ObjectResult(Of CreateErsSalesAddSubmissionXmlByDateRangeResult)
        Dim startDateParameter As ObjectParameter
        If (startDate.HasValue) Then
            startDateParameter = New ObjectParameter("startDate", startDate)
        Else
            startDateParameter = New ObjectParameter("startDate", GetType(Global.System.Nullable(Of System.DateTime)))
        End If
        Dim endDateParameter As ObjectParameter
        If (endDate.HasValue) Then
            endDateParameter = New ObjectParameter("endDate", endDate)
        Else
            endDateParameter = New ObjectParameter("endDate", GetType(Global.System.Nullable(Of System.DateTime)))
        End If
        Dim VesselPlnParameter As ObjectParameter
        If (Not VesselPln Is Nothing) Then
            VesselPlnParameter = New ObjectParameter("VesselPln", VesselPln)
        Else
            VesselPlnParameter = New ObjectParameter("VesselPln", GetType(String))
        End If
        Return DirectCast(Me, IObjectContextAdapter).ObjectContext.ExecuteFunction(Of CreateErsSalesAddSubmissionXmlByDateRangeResult)("FishTrackerProfessionalEntities.GetLandingsToBePurchasedByDateAndPln", startDateParameter, endDateParameter, VesselPlnParameter)
    End Function

它是这样称呼的；

 Using ftpe = New FishTrackerProfessionalEntities
        Try
            Dim result = ftpe.GetLandingsToBePurchasedByDateAndPln(StartDate, EndDate, VesselPln)
            xmlValue = String.Join(String.Empty, result.Select(Function(r) r.XMLF52E2B6118A111d1B10500805F49916B))
        Catch Ex As Exception

开始和结束日期是日期类型的属性。

【问题讨论】：

这很可能是 @VesselPln 参数值或您传递它的方式存在问题。

@RBarryYoung 在这两种情况下（ssms 和来自代码，它都作为一个字符串传递。在我提出的问题中，字符串是“RX89”的结果的情况下。基础数据类型VesselPln 是 Nchar(10)。

您应该向我们展示这两种情况的调用代码。也就是说，明确地向我们展示您是如何在代码中和从 SSMS 中调用 SPB。

已添加相关代码。

您可以运行探查器跟踪以确保它不会强制转换变量或替换为空字符串而不是传递 null 吗？

【参考方案1】：

问题很可能出在参数上，根据我的经验，日期总是一团糟..

最常见的问题是月日反转，它发生在各种场景中，例如日期和日期时间之间的隐式转换。 看看这个：

declare @d1 date = '2016-02-03'
declare @d2 datetime = '2016-02-03'
select FORMAT(@d1, 'yyyy-MMMM-dd') ParDate, FORMAT(@d2, 'yyyy-MMMM-dd') ParDateTime

结果很有趣：

ParDate             ParDateTime
2016-febbraio-03    2016-marzo-02

所以你可以尝试调试你的SPB，修改SPB中PATH ('Owner')的WHERE子句。 暂时解除@startDate/@endDate 和@VesselPln 的条件

-- AND (LandingDate1 BETWEEN @startDate AND @endDate)
-- AND LandingHeaders.VesselPLN = RTRIM(@VesselPln)

然后尝试从您的应用中调用它，它应该会返回所有结果。 然后在@VesselPln上重新添加条件，测试一下，我觉得还是会输出一些东西。

如果没有，您已经发现了问题，可能与多字节字符串 nchar(10) 相关，或者不太可能与 ansi 填充和尾随空格相关。

如果是，请将@startDate 和@endDate 添加到PATH ('Owner') 的SELECT 部分，以查看SPB 如何查看它们：

FORMAT(@startDate, 'yyyy-MMMM-dd') as '@StartDate', 
FORMAT(@endDate, 'yyyy-MMMM-dd') as '@EndDate',

这样你应该在你的 xml 输出中看到什么问题。

我希望这会有所帮助。
